MHC and APC

APC and MHC Review

QuestionAnswer
What do you call any protein or recognizable structure on the membrane of a pathogen? marker
What is the process of a phagocyte consuming a pathogen? phagocytosis
What do you call the process of breaking a consumed pathogen into small chunks? lysing
Which genetic materials are taken from the pathogen and presented on the outside of the phagocyte membrane? peptide chain or polypeptide chain
The peptides taken from the pathogen are bound to a special presenting protein on the outer membrane of the phagocyte in the form of what structure? major histocompatibility complex
What kind of cell has the major histocompability complex on its membrane? phagocyte, macrophage, neutrophil, dendritic cell
What kind of cell has a membrane bound antibody on its cell membrane? B cells
Phagocytosis is an example of innate or adaptive immunity? innate
When a B cell has discovered a pathogen whose epitope fits one of its variable portion segments of an membrane bound antibody, what happens? 1) the embedded membrane antibody and the attached pathogen are ingested 2) the B cell begins making memory and plasma B cells
When released from an activated B cell, what do plasma cells do? make antibodies to fight the pathogen
The antibodies released from a plasma cells have what impact on pathogens when it locates them? binds to them- making it easier for phagocytes to find them also making it impossible for the virus to infect a cell
B cells lyse captured pathogens and present their antigens on the cell walls- just like Phagocytes do. What do you call this class of cells who create mahor histocompatibility complexes? Professional Antigen Presenting Cells

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
